CarPlay Disconnecting - iPhone XS Max

Same problem. 2018 Audi A5 Sportback. Switched from an iPhone X running the iOS 12 public beta. No problems. Upgraded to an iPhone XS Max (256/AT&T/gold) running 12.0. Same problems as OP. Tried hard resets: did nothing to solve the problem. Did a full restore: nothing. Wiped the phone and started from scratch: nothing. Went to Genius Bar, reported the problem, got a replacement unit (same specs): nothing. Upgraded to 12.1 public beta 2 (the one that’s supposed to fix the charging problem, figuring it was related): nothing. Problem does not happen when plugging in my old X, my wife’s 7S Plus, or my daughter’s 8, all running 12.0.

There does seems to be some correlation between when the car’s Wi-Fi is doing something and when the CarPlay cuts out. Trying to figure out whether there’s a way to disable it (turning it off in the Audi settings doesn’t appear to be enough). Weirdly, if I put the phone into Airplane Mode, then connect it to the USB port, the problem doesn’t occur. (Of course, this is useless, since the phone is now offline.) But if I wait about five minutes and then switch it back to regular mode, the problem didn‘t return. Only tried this once, so I need more testing. Not sure what that would mean, other than to suggest a conflict betwen the iPhone’s Wi-Fi (or Bluetooth, or both) and the car’s.

I have had some success by deleting Google Maps from my phone. Not a fan of this solution but for now it has been the only thing that has worked...it is driving me cra cra!

Able to use Waze and listen to Apple Music and podcasts now...let me know if this works for you.

Set up another support call for tomorrow. I'll post if I learn anything new.

Dear all.

I'm writing from Chile, South America.

Have the same problem with a new Iphone XS connected to my 2018 Audi A5 Sportback. iOS 12.0.1

Carplay randomly disconnects. Sometimes every 10 minutes, sometimes every 10 seconds, etc, etc….

Tried all the possible solutions suggested in this community, but nothing work at the moment.

Today a tried turning off WIFI and Bluetooth in my iphone before connecting it to the car (USB 1) and finally I got a 30 minutes trip with no disconnections (Carplay Waze and Spotify working ok) .

I will try to continue testing this way during next days. Hope this works….

Hello,

Same problem here between XS Max and Audi A5 2018.

Only this trick has worked for me:

1-put iphone in airplane mode.

2-connect iphone to the usb port of Audi console.

3-wait 2-3 minutes and remove airplay mode.

Doing this carplay did not suffer disconnections in 45 minutes (all the trip).

Do you know if all usb voltage meters solve temporary this issue? I don’t want to waste the money...

Thanks!

i’ve been having the same problem recently. i read elsewhere that people have found a link between this problem and having a VPN profile on your phone. i’ve just deleted mine so hopefully that helps.

After much frustration I ordered a USB voltage meter and its worked since. Hasn’t cut out once. iPhone XS Max.

Here is the one I bought.

Nothing is going to fix this (with exception of some people having success with USB meters), until Apple releases a software fix. iOS 12 introduced a power management issue it needs to solve. Our best bet for anyone with this issue, is to report it to Apple support if you haven't already done so.

Spoke to Apple support, here are all of the troubleshooting suggestions I have been provided:

(1) Forget vehicle in CarPlay and then reconnect the phone

(2) Go to Settings/Screen Time/Content & Privacy Settings:

• • Enable Content and Privacy Settings if disabled
  • Go to Allowed Apps
  • Ensure that CarPlay is Enabled

(3) Renaming the phone

• • Forget the Car stereo from Settings/General/CarPlay
  • Forget the iPhone from the Car Stereo
  • Rename the iPhone in phone settings
  • Reconnect the iPhone to the car stereo

(4) Test with a shorter apple lightning cable.

Results:

I tried (1) this morning and CarPlay worked for a few mins then disconencted 3 times within 20 mins while listening to music that was playing from so it made no change.

(2) Just done this and need to take a drive to test it out. Will report later on after I do so. This suggestion came from the Apple tech that called me from the scheduled call.

(3) Not tried yet. This suggestion came from the Apple online chat technician. I want to try (2) for a while to help narrow down which solution solves the issue.

(4) I already use a certified 6" lightning cable (works fine with CarPlay on my other iPhone)

My setup:

2018 Jeep grand Cherokee Summit

iPhone XS MAX IOS 12.1.2

iPhone 7 Plus IOS 12.1.2

This is what I posted if it helps:

I think I found the problem with the disconnect in CarPlay.

I have a loaded KIA 2018 Stinger GT2. I have Had this problem for 4 months.

Are you ready .... Apple (iPhone) MAPS has been causing the issue.

I stumbled across it when I turned off the Radio and closed the apps on my iPhone.

Apple Maps popped up on my Radio. (Not the Nav that comes with the Radio) It was running. I didn't open it ! it must have been running in the back round using resorces. I deleted the App from my iPhone. Thank god (Apple), lol allowed users to uninstall there apps.

Once I did that I rebooted the iPhone connected back using the same Lightning Cable and proceeded to see if every thing was still functioning, it was, then I took a drive. Everything is working perfectly. Even all the information for Waze, SiriusXM and other music providers are working great.

Been working with no issues for about 10 days straight. WOW, what a relief.

Funny thing though, every once and a while a little window comes up and reads "Apple maps needs to be installed. go to the apps store". LOL.

Wow you should really get your MMI updated. I had some iPhone X CarPlay disconnects problems when I was on 1117, which are now gone on 1329. 1329 is smoother overall and CarPlay opens faster when you start the car.

I'm happy to say my iPhone XS Max disconnects are also resolved with the new IOS firmware

Don't give up yet. Please try your iPhone X on iOS 12.1.3 in your Audi regardless of the MMI version.

I've had nothing but success--no dropped connections at all--with iPhone XS and X since the update. The last time I may have had an update to my MMI was August 2018 when I had my vehicle in for an inspection. I never regarded MMI as the culprit.

Finally, after about two days in my Audi workshop the problem with CarPlay constant disconnecting in my A4 Allroad is solved, hopefully...At least it worked constantly all the drive home flawlessly👍.

According to workshop, it was a bad connection between the MMI actuator and stereo module causing the USB ports to switch on and off. It was not related to iOS, iPhone, or type of cables.

Thans for all your support with my troubleshooting!

After spending 60 minutes troubleshooting with Apple Customer Service, I seemed to have solved the problem after suffering it for 4 months. The solution is as follows, and so far the problem hasn't come back (fingers crossed):

1- Delete or forget all phone devices from your car

2- Go to settings and delete or forget all cars from your phone Bluetooth and CarPlay connections

3- Go to settings, general, about,name and rename your phone. Just change whatever name you phone have on this field.

4- Re-pair your car and phone again

5- Enjoy, and hopefully it works for you as well it does for me.

6- You're welcome!

My 2018 iphone XS has the same issue, doesn't matter if its the Max or not. $5 fix, buy usb voltage meter and plug it in the usb slot, no more disconnects. The item is the size of a usb thumb drive
